BACKGROUND OPERATIONS
Squelch Level
Squelch is a function that eliminates the noise when no signals are being received.
Setting the higher squelch level allows you to monitor only stronger signals.
Usually start from level zero (the squelch is open and hear the noise), increasing
the level and when the noise is gone, set just 1 level higher than the
currentstatus. For example the noise is cut at level 3, set the level to 4 and exit.

Battery Save
This function prevents useless battery consumption by switching the power ON/OFF at a xed ratio if
there is no key operation or receiving signal for a continuous period of 5 seconds or more. Higher OFF
time (1:4 setting) saves more amount of battery but may cause slight delay on receiving. The Battery
Save function is temporarily suspended when a key is operated or a signal is received. The display
remain unchanged even the BS function is in the OFF cycle.
